| Short description | Melaleuca citrolens and/or Eucalyptus pruinosa low open woodland on sandy plains |
| Structure code | Low Open Woodland |
| Description | Melaleuca citrolens and/or Eucalyptus pruinosa low open woodland often with Melaleuca viridiflora and occasional Melaleuca stenostachya with a mixed shrub layer of Petalostigma banksii, Carissa lanceolata and Acacia spp. over a ground layer of Triodia pungens. Occurs on small tertiary sandplains. Not a Wetland. (BVG1M: 21b). Vegetation communities in this regional ecosystem include: 1.5.11x1: Eucalyptus chlorophylla, Melaleuca viridiflora and Melaleuca citrolens woodland. Mixed ground layer of tussock grasses +/- Triodia bitextura. Occurs on soils with sandy surfaces over clay in the far north of the bioregion. Not a Wetland. (BVG1M: 21b). |
| Fire management guidelines | SEASON: Storm season to early dry season. INTENSITY: Low to moderate. INTERVAL: 4 - 10 years. Ensure some areas are long (10-20 years) unburnt. Adjust intervals/frequency according to rainfall-drought cycles, fuel accumulation and previous fire history. INTERVAL_MIN: 4. INTERVAL_MAX: 20. STRATEGY: Ensure burns are undertaken across the landscape at a range of frequencies to create a mosaic of times since fire. Apply numerous small burns every year to achieve a mosaic and reduce risks of wildfire across vast areas of the landscape. Maintain burnt areas < 20%. ISSUES: Rainfall is a major factor affecting spinifex growth, such that a very wet year or a series of wet years may boost the spinifex fuel load leading to the possibility of extensive wildfire in subsequent years. |
